Kodo progress?

Question

Hello all!
I was wondering whether anyone representing TechTrader could update us on
how progress is proceeding on Kodo?!?! In particular, integration with
application servers, etc.
Furthermore, is the JSR for JDO likely to reach final status anytime soon?
That is obviously a barrier to wholesale adoption of JDO in production
environments!
I must admit, I wish there was a higher level of posts on this list. This
is an interesting technology and deserves more discussion!
Regards,
James W.

Hi folks,
The new beta of Kodo JDO is now available!
We've been busy trying to get the latest version of JDO ready and
packaged. We apologize for the delay in getting you updated information
regarding the status of Kodo. We've made a number of changes to Kodo
including the introduction of the Enterprise Edition so we've decided to
extend the beta period. To download this new beta, please go to
http://www.techtrader.com/products/jdo.html
<http://www.techtrader.com/products/jdo.html> .
The following email is being sent to the JDO announce distribution list
announcing Kodo JDO Standard Edition Beta 2.0 and Kodo JDO Enterprise
Edition Beta 2.0. Both will be available for download from the site
today and the license is good till August 25, 2001.
We again look forward to receiving feedback on the product from you.
You can send feedback or support questions to [email protected].
The Kodo Product Team
TechTrader, Inc.
TechTrader is excited to present the latest versions of Kodo JDO:
- Kodo JDO Standard Edition Beta 2.0; and
- Kodo JDO Enterprise Edition Beta 2.0
The Kodo JDO Standard Edition Beta 2.0 incorporates much of the feedback
that we have received from our loyal beta testers. Thank you. In
addition, we've introduced a number of new features including support of
n-many relations and JNDI lookup. The current release of Kodo JDO
Standard Edition more fully supports the Proposed Final Draft of Sun's
Java Data Objects Specification 1.0.
The introduction of the Kodo JDO Enterprise Version represents a growing
need for tools and features that are needed for larger scale usage of
Kodo. In addition to all of the features in the Standard Version of
Kodo, the Enterprise version offers PersistenceManagers that can
transparently synchronize with global J2EE Transactions. Additional
enterprise features are being developed. Please let us know what new
features you would like to see in the Enterprise Version of Kodo JDO as
we take our users feedback very seriously.
PREVIOUS KODO JDO USERS
We highly recommend upgrading to Kodo JDO Standard Beta 2.0 or
Enterprise Beta 2.0. Your version of Kodo expires on July 15, 2001 - to
continue using Kodo you must upgrade.
Detailed upgrade instructions are included in the download in the file
UPGRADE.txt. Quickstart instructions follow:
- Replace the shell/bat scripts that shipped with the previous version
of Kodo with those in the bin/ directory.
- Replace the jar libraries that shipped with the previous version of
Kodo with those in the lib/ directory. Note that some new libraries have
been introduced; therefore, these should be added to your CLASSPATH.
Read the rest of this document for information on changes that might
require modification of your application.
New Features
- Maps with user-defined persistent object values can be persisted
(n-many relations).
- Static inner classes can be persisted.
- Queries support the use of containsKey() and containsValue() for Map
fields.
- Queries support ordering declarations.
- The SchemaTool's schema migration capabilities have been enhanced.
- The SchemaTool offers the option of automatically maintaining the list
of persistent types for the system.
- Schema generation can be customized through JDO metadata.
- The standard javax.sql.DataSource is used to obtain connections.
- Connection pooling has been enhanced, and new pooling parameters have
been added (timeout time, autoreturn time).
- The ObjectId helper class has been introduced to map opaque JDO OID
values to and from primitive long values.
- PersistenceManagerFactories can be stored in JNDI, including JNDI
trees that are replicated over multiple JVMs.
- PersistenceManagers can transparently synchronize with global J2EE
Transactions (Kodo Enterprise Edition beta only).
Bugfixes
- Row-level locking is now performed within pessimistic Transactions.
- Object ID generation is now done using the database by default.
- Globally unique primary key values are no longer required (per-class
only).
- Inserting new instances of classes mapped to an existing schema
without a class indicator column no longer throws a
NullPointerException.
- Numerous minor fixes.
Notable Changes
Users of previous beta versions of Kodo should scan the user guide in
the docs/ directory for new information included with this release.
Of particular note:
- The schematool can now automatically maintain a list of persistent
classes; the <persistent-types> array in system.prefs is not needed.
This is covered in the Database Setup chapter of the user guide.
- The syntax for using the schematool has changed. This is covered in
the Database Setup chapter of the user guide.
- The syntax for mapping classes to existing database tables has
changed. This is covered in the Using Existing Schema chapter of the
user guide.
- The Runtime Use chapter of the user guide covers new runtime options
available, such as JNDI storage of the JDBCPersistenceManagerFactory and
safe conversion of JDO OID values to and from primitive long values.

Hi James and Mike
This is the info I got last week from TechTrader:
Hi Christof,
Thanks for downloading and using Kodo.
We are planning on releasing a version of Kodo before the July 15th
deadline -
it may be a final beta version, but most likely it will be the
production
version. We'll announce the release plans on our JDO Announce listserv
(Just
send an email to [email protected] with "subscribe" as
the
subject).
We are planning on retailing Kodo at $700 per developer seat. However,
during a introductory promotion, we plan on selling Kodo for $299 /
developer
seat. Included in this price is 30 days email support and 30 days of
free
upgrades. There will be no run-time royalties.
Additional support / upgrade packs may be purchased for $500 for 1 year
of
email support and free upgrades.
Let me know if you have any questions. I've cc'd this email to our
sales
folks in case you'd like to follow-up with them.
Thanks and let us know if you have any additional questions.
